Cheap flights to San Francisco! Air New Zealand has under $800 Return from SYD, and low prices from elsewhere too.
How to find dates…
1) Search directly on skyscanner, or as I used flightscout: https://flightscout.co/au/cheap-flights/anywhere-to-san-fran… – seems to be a dollar or two cheaper than the advertised FS price though once you get to skyscanner.
2) If on flightscout, choose departure city and see available cheap dates.
